ELIMINATION or FIBR-OUS WASTE FROM MACHINES. "I.

Application filed September 16, 1926, Serial No. 135,735, and. inGermany October 31, 1925.

In many machines for the production of fibers and fibrous material, andfor the weaving or other treatment of such fibers or fibrous material,the efficiency of the moving parts is often impaired by flying wastewhich frequently accumulates on the moving parts in the form of flocksor flocculent masses which have heretofore been eliminated only withdifliculty and with considerable loss of time.

Such flying waste accumulates particularly on the warp thread guards forlooms, and enters the apertures of the stop-motion so as to prevent orinterfere with the dropping movement of the individual stop motions.Flying waste also accumulates at the cross rods in the space between thelost motion rod and the crossing of the warp, and which is utilized forthe purpose of effecting a sub-division of the number of threads lyingone next to the other, to one half their number, by dividing the warpthreads when the warp is very close together.

In carrying out my invention I eliminate such flying waste in a verysimple and effective manner, by means of a tool which is adapted to berapidly rotated, and which may be brought to a position adjacent to thefront or the end of the collected fibrous material. The tool is soconstructed that by its rotation in engagement with certain of thefibers, it will twist them together into a sort of roving and draw themfrom the machine.

If for instance one desires to clean the stop-motion, he can remove theflying waste from a group of the parts at the same time. The twistingprocess will continue within the group from the side at which it begins,to the far'side. The roving or twisted mass may then be easilyextracted. The flying waste collected in such rovings may be reused.

In the accompanying drawing I have illustrated by way of example oneapparatus embodying my invention, and which may be employed in carryingout my improved process. In these drawings:

Fig. 1 is a side elevation of a group of warp thread guards, and

Fig. 2 is a side view thereof.

In the construction illustrated there are a plurality of stop-motions p,each of which has an upper aperture 0 by means of which it is suspended,and also has a lower aperture or mold Z through which extends theguiding rail 7. These are standard parts of a loom. During the operationthe waste material 4; collects in the mold l, and prevents or interfereswith the dropping movement of the stop motion, and often prevents theproper operation of the device. This waste material extends through theapertures of all of the parts 7) above the rail f.

In order to eliminate this waste material in the course of the operationI provide a tool 1'; which may be a hook or a clamp of pincher-likeconstruction. This is connected to a shaft 11) which is preferablyflexible. The tool 7': is brought into engagement with one end of therow or flock of waste fibers, and may be secured to some of them ifdesired. The rotation of the tool causes the fibers to twist togetherand become interconnected in a roving, so that when the roving is formedit may be pulled from one end, and all of the waste material removedfrom all of the StOlPIIlOtiOlIS p. The work can be done very quickly andin some cases it is not necessary to interrupt the operation of themachine. All that is necessary is to drive the flexible shaft from anysuitable source of power, as for instance a small electric motor, and toengage the tool with the end of the elongated mass of fibrous material.If desired the shaft may be driven by a portable motor, so that theworkmen may carry the motor and the shaft and go from one machine toanother in cleaning them.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. An apparatus for the elimination offibrous flying waste from machinery, which includes a tool adapted toengage with thewaste, and means for rotating the tool to form the wasteinto a roving.

2. A process for the elimination of fibrous flying waste from machinery,which consists in engaging the waste by a rotatable tool and therebyforming the fibers of the waste into a connected rovin whichmay bereadily fibrous waste from looms, includingaflexible withdrawn from tl emachine. shaft and a tool connected thereto and driven 3.
